Esophageal cancer begins in the wall of esophageal that grows outward. When it spreads through your esophageal way, it reaches to your lymph nodes. The lymph nodes are the organ like a tiny and bean shape that helps to fight infection. It spreads gradually to the lungs, stomach, and liver along with other parts of your body. The esophagus is the part of your gastrointestinal tract. If you swallow it squeeze together of the wall of the esophagus that pushes food down to the stomach. But, when healthy cells change, begin tumor in the esophagus. All tumors are not cancer while some of them are benign other are cancerous. A cancerous tumor is malignant that means it may grow and spread to other parts of your body. Here you’ll learn about esophageal cancer and esophageal cancer causes in details.

What is Esophageal Cancer?
Cancer begins when cells in your body start to grow without control. Cells in nearly any part of your body can become cancer and can reach to other locations of your body. It’s important to know the function and structure of esophagus before of understand esophageal cancer. The esophagus is a muscular and hollow tube that joins the stomach and the throat. If you eat food or liquids, it travels through the lumen and reaches to the stomach. There is a special ring in the upper part of the esophagus that calls upper esophageal sphincter. And the lower part calls gastroesophageal. When healthy cells change, begin tumor in the esophagus. All tumors are not cancer while some of them are benign other are cancerous. A cancerous tumor is malignant that means it may grow and spread to other parts of your body.
What are Esophageal Cancer Causes?
You’ll not find any definite esophageal cancer causes because there is no exact cause is found. But, some certain factors that make it more likely. Doctors and scientists believe these risk factors that are alcohol or tobacco may cause esophageal cancer. Moreover, it has long-term lining irritation of the esophageal, such as reflux, achalasia, Barrett’s esophagus etc.
Besides, there is another great factor of the DNA that believes to act more in this concern. But, tobacco and alcohol are more dangerous with the combination, tobacco alone. They can harm certain genes, such as start and stop of cell growth, to go wrong. It begins to produce abnormal cells that form a tumor. Gradually the cells may go to nearest tissue and other organs of your body. DNA changes can alter these into genes that support cell division that calls oncogenes. Some genes that slow down cell division or make cells die at the right time and are called tumor suppressor genes. DNA changes can turn off tumor suppressor genes, and lead to cells growing out of control.
What are the Risk Factors for Esophageal Cancer?
Since there is no definite cause of esophageal cancer, but researchers find some risk factors to commit it. The factors that believe to be responsible for cancer calls risk factors. Esophageal cancer also has many risk factors that know at least. They include Age, Gender, Tobacco and alcohol, Obesity, Diet, Tylosis, Workplace exposures etc.
